Strategy, the company led by Michael Saylor, did not buy any Bitcoin between August 31 and September 7. Instead, it spent $176.3 million buying back its own STRC preferred stock, according to an 8-K filing with the SEC on September 8.

The company repurchased 1,810,885 STRC shares. It also doubled the ceiling on its Digital Credit Securities Repurchase Program, from $1 billion to $2 billion. Every dollar came from the company's USD Cash reserve, not from selling Bitcoin or raising new capital.

Strategy's Bitcoin treasury stays unchanged at 845,050 BTC, worth about $66 billion at current prices. The position cost $63.6 billion to build, at an average price of $75,412 per coin. That holding equals more than 4% of Bitcoin's total 21 million supply cap.

The pause follows a rare active week. Just seven days earlier, Strategy bought 4,603 BTC for roughly $370 million, its first purchase since mid-June. Before that, the company had gone about ten weeks without adding to its treasury, an unusual gap for a firm that built its identity on buying Bitcoin almost every week since 2020.

The STRC repurchase points to a different problem: the preferred stock is trading below its intended value. STRC was designed to hold near its $100 par value, similar to a money-market instrument. On September 8, it traded around $97.70, a discount of about 2.3%. Buying back shares below par is a way to support the price and signal confidence to preferred shareholders.

This is not new behavior. Strategy has run STRC buybacks for several weeks running, and in August the shares traded as low as the mid-$80s at one point, a much steeper discount than today's. The August 2026 investor briefing raised the STRC dividend rate from 11.5% to 12% specifically to make the security more attractive and pull its price back toward par.

The deeper issue is mNAV, the ratio between Strategy's market capitalization and the value of the Bitcoin it holds. For years, MSTR traded at a heavy premium to its Bitcoin, sometimes 2x or 3x, because investors paid extra for leveraged exposure and Saylor's buying reputation. That premium let Strategy issue new shares above the value of its Bitcoin, buy more Bitcoin with the proceeds, and increase Bitcoin per share for existing holders.

That mechanism weakens badly once mNAV falls toward 1.0x or below. In late June 2026, Strategy's basic mNAV dropped below 1.0x, meaning the market valued the company at less than its Bitcoin holdings alone. By early August it sat around 0.68x to 0.77x on a basic basis, though the more complete enterprise measure, which includes debt and preferred stock, stayed closer to parity. As of this week, mNAV has recovered to around 1.13x.

When mNAV compresses, issuing new common shares to buy Bitcoin dilutes existing shareholders instead of benefiting them. Preferred stock issuance carries its own cost: each new preferred share creates a fixed dividend obligation that sits ahead of common stock in the capital structure. Strategy now carries four listed preferred series, STRK, STRF, STRD, and STRC, worth roughly $15 billion combined, plus about $6.7 billion in convertible debt.

The choice to buy back discounted preferred shares instead of Bitcoin reflects capital discipline rather than retreat. Repurchasing STRC below par effectively locks in a return, since the company retires debt-like obligations for less than their face value. It also reduces the fixed dividend burden the preferred stack imposes on the balance sheet.

The tradeoff is that Strategy's core pitch to investors has always centered on relentless Bitcoin accumulation. A multi-week pause, paired with active buybacks elsewhere, raises the question of whether the company can keep growing its Bitcoin per share at the pace it has in prior years. MSTR common stock fell more than 3% on September 8, even as STRC held close to flat.

MSTR stock has still climbed about 45% over the past month, tracking Bitcoin's recovery from lows near $63,000 to highs above $82,000. Year-to-date, however, the stock remains down more than 7%, a reminder that the equity has moved independently of Bitcoin's own price action for much of 2026.

Strategy remains by far the largest corporate Bitcoin holder, but it is no longer buying in isolation. Other treasury companies added Bitcoin in the same week Strategy sat out. Strive increased its holdings by 1,375 BTC, funded partly through its SATA preferred structure, and Capital B also added to its reserves.

The pattern across the sector suggests that smaller, newer entrants are still in accumulation mode while Strategy, the pioneer of the corporate Bitcoin treasury model, is focused on repairing its own capital structure first. Whether that shift is temporary or reflects a more permanent change in strategy will depend largely on where mNAV settles in the months ahead.
